Normally in industrial program since the programe size is more..we cant assign tag in an ob. So to increase the program performance we will create logic in an FB and call from an FC and assign tag inside an FC or vice versa...
Is my understanding correct?
Hey,
No, this is not true except in cases that we are strictly limited with our memory resources. Otherwise, it does not seem a logical reason for implementing such an architecture for our software. As I explained in the previous thread, the purpose of using an FB and FC are something else.
I previously gave a detailed answer to your question in a separate thread with the same title but unfortunately, I see the thread has been deleted.
